Overview
Including a rich history dating back to the 1870s, the 16 block area known as the Lake Cherokee Historical District showcases a vivid representation of the early architecture of established Orlando’s first residents. With such a significant past, it’s important to protect and cherish these historical assets in preserving the character and roots of Orlando. Built directly offshore of Lakes Cherokee and Lucerne, these properties are, however, susceptible to rising waters. Poor drainage from an insufficient storm sewer and standing water due to street erosion, has become a prevalent concern. These conditions pose a considerable threat to surrounding homes and businesses as flooding not only promotes pollution, but consequently causes erosion damage. Erosion causes roads to deform, creating potholes, which is amplified as many local roads are made of brick which can easily become disjointed. Similarly, flooded sidewalks and house foundations can cause cracks from shifts in the concrete which could make these structures unsafe, jeopardizing the standing architectural history of the Lake Cherokee Historical District. In response to these growing issues, the City of Orlando developed a plan to install a new storm sewer with a connection from Lake Lucerne to Lake Cherokee. This will help to mitigate flooding issues by utilizing both lakes as a means of detention concurrently The further installation of two Nutrient Separating Baffle Boxes® at Lake Cherokee will aid in filtering stormwater of debris which can impede water flow, causing localized flooding. Orlando’s implementation of said improvements will yield much cleaner runoff and minimize erosion issues, thus preserving Orlando’s architectural assets for further decades to come. |

Lake Connection Combines Runoff Control Components
Extensive planning for the Southeast Lakes drainage improvement project arose in January of 2016 as engineering firm Singhoffen & Associates, Inc prepared a complete site evaluation and construction plan. The plan consisted of the construction a storm sewer lake connection from Lake Lucerne to Lake Cherokee as well as two NSBB stormwater treatment vaults as a means of better controlling runoff flow through the system. Because Lake Cherokee can often become overwhelmed and inundate the surrounding neighborhood, it was determined that both NSBB vaults were to be installed at the North end of the lake. By utilizing the extent of both lakes as detention systems and the filtration ability of the NSBB vaults, runoff can more quickly drain from streets unimpeded, during high flow rain events. |
Finished installation of one of two NSBB™ treatment vaults at Lake Cherokee which will vastly decrease flooding and erosion issues associated with local homes, businesses and the brick roads surrounding the lake, thus working to preserve the architectural history of the district.

NSBB's™ Power Preservation of Orlando's Past
The Nutrient Separating Baffle Box or NSBB is a hydrodynamic separator treatment device which specializes in online sediment and debris capture and containment without typical associated headloss and scouring. Both designed and manufactured by Suntree Technologies Inc®, an Oldcastle Infrastructure™ company, the NSBB has a suspended lidded screen system that prevents nutrient leaching and static water from turning septic due to prolonged contact with bacteria ridden trash, debris or organics. The inclusion of SkimBoss® floating skimmers with attached StormBoom™ filters will prevent the passing of debris during high flow events and absorb any trace hydrocarbons. The added HydroSlide® service systems allow for efficient, lower cost servicing without vault entry via a pipe system that conveys pressurized water from a vacuum truck to the bottom of the vault, washing any sediment toward the vacuum line for removal. These structures will effectively manage flooding issues by capturing and containing debris while also contributing as stormwater detention structures. Both the model 8-14 and model 8-16 NSBB vaults were installed between 4/12/17 and 4/14/17. The installations went smoothly without interference from storms, thus completing the project as a joint effort between the J. Malever Construction Company, Singhoffen & Associates Inc, Ferguson Waterworks, and Suntree Technologies Inc. The completion of this drainage project is an important measure to resolve the chronic flooding and erosion issues within the Lake Cherokee Historical District. Orlando’s efforts will ensure that the vulnerable historic brick roads and homes remain as standing reminders of the expressive architectural eloquence of Orlando’s past for residents, visitors and the like to enjoy for generations. |
The Lake Cherokee Historical District incorporates a rich architectural history with a survey of many different architecture styles dating back to the 1870's. Structures such as the Cherokee School, Poyntz-O'Neal House and Dr. Phillips House showcase the diverse character of Orlando and richness of a blend of styles like Mediterranean Revival, Queen Anne and Neoclassicism respectively within a mere sixteen block area.
